The shading cue in context

J Wagemans, AJ Van Doorn, JJ Koenderink - i-Perception, 2010 - journals.sagepub.com
The shading cue is supposed to be a major factor in monocular stereopsis. However, the
hypothesis is hardly corroborated by available data. For instance, the conventional stimulus …

[HTML][HTML] Light fields and shape from shading

AJ van Doorn, JJ Koenderink, J Wagemans - Journal of Vision, 2011 - iovs.arvojournals.org
From a theoretical point of view, the use of the shading cue involves estimates of the light
field and thus observers need to judge the light field and the shape simultaneously. The …
